The key parameters we look into are infill %, layer height and infill pattern. In the main body of this study, we provide a detailed description of the influence these parameters have on max stress, elongation at break, rigidity (Young Modulus) and yield stress.
A black box theater is a theater with a very simple, unadorned design which makes it an extremely flexible space. These theaters began to proliferate in the 1960s, probably deriving from practice spaces used by major theater companies and universities with large theater programs.
System theory. 1  The open system theory is the foundation of black box theory. Both have focus on input and output flows, representing exchanges with the surroundings. 2  The observed hydrograph is a graphic of the response of a watershed (a blackbox) with its runoff (red) to an input of rainfall (blue).
